# Hysteresis loop in Griffiths' Introduction to electrodynamics

In Griffiths' Introduction to electrodynamics there's the following Hysteresis Graph:

Shouldn't it be $$10^{-4}$$ instead of $$10^{4}$$ on the x-axis?

• $\mu_o=4\pi\times 10^{-7} Vs/Am$ so if $H \approx 100A/m$ then $\mu_o H \times 10^{4} \approx 1$ – hyportnex Jun 11 at 15:30
